Wow, congrats on finishing the week! I have been considering doing the same thing and came across your page. How long did it take for your focus to go back to normal and the dizzy feeling to go away? Same day? Did you ever go back to that library to see if you could recognize anything?

Hi Mike,

Glad to hear you're also interested in doing something like this. If you do it, I'd love to hear about your experience.

My eye focusing was pretty bad right when I opened my eyes that night, but in the morning when I walked around my neighborhood it was pretty fine. The dizzy feeling also subsided by the middle of the next day or so.

One thing I didn't write about is that I got into a pretty serious bike accident when I biked into the lab that morning. I tried jumping a small curb which is normally no problem, but my timing was way off, I jumped too early, landed, and then my bike hit the curb. I flew over the handlebars and landed on my face and hands. I felt concrete scrape under my 2 front teeth. All in all, I was pretty banged up and chipped a bone in my wrist (first broken bone of my life). Everything healed up fine, but the point is that the hand-eye timing may take a while longer to get synchronized again.

I haven't gone back to the library yet. I should.

Great job on the experiment! I was wondering, if visual deprivation even for just a few hours can improve someone's eyesight (did I get that right?), is that a permanent effect or is it just temporary? If it is only temporary, how long do you think the effects of having an improved vision will last? Lastly, if the effects are temporary, do you suggest that I do visual deprivation regularly just so I could prolong the experience of an improved vision? Thank you and I hope to hear from you soon! I hope this improves my vision especially at night since I have a hard time seeing at night... I think it's something called night blindness

Hi Olivia,

I don't think the right way to think about the effect was visual deprivation had on me was to improve my vision. It did make me very sensitive to depth and color perception, but I don't think it improved my acuity or night vision. You could try it to see for yourself. Also, I think each episode of deprivation might need to be pretty prolonged, perhaps 1-2 days at least.

Alright! I will definitely try it for a day. I tried it for an hour and I ended up falling asleep. Thank you so much :)
